Posted: 1/24/09 Title: Trout Dissection Lab Purpose: The purpose of this lab is to see how the body systems of our Brown Trout was effected because of the Chlorine. Hypothesis: I think that if we look at the liver then we will see that it is totally "shot" because the chlorine attacks the liver. Variables: Independent- the Fish
Dependent- amount of Liver Poisoning
Control-The Time frozen, Temperature of the Location where frozen, amount of artificial and natural Light
Constant- none Best State: The best state would be if we could see the liver in great detail. Materials: Brown trout, dissection microscope, dissection kit, Trout liver picture/ diagram.
Procedures: 1 Remove the fish from the freezer.
2 Let it thaw for a small period of time.
3 Make an incision below the jaw.
4 Open up the incision and pin it down.
5 Compare it with your diagram.
6 Remove the liver.
7 Disect the liver under a microscope. 8 Compare it to a normal trout liver.
Results: There are currently no tables or graphs because we have not yet started the dissection Conclusion: There is no conclusion since we have not finished the experiment. Links: http://www.moondragon.org/health/disorders/chempoison.html
